Solve the system:
n+d+q=46
n=q+11
10d=25q-100
From the 3rd -->d=2.5q-10
The 1st: (q+11)+(2.5q-10)+q=46

q=10
n=21
d=15

Suppose that Maria has 120 coins consisting of pennies, nickels, and dimes. The number of nickels she has is 14 less than twice the number of pennies; the number of dimes she has is 22 less than three times the number of pennies. How many coins of each kind does she have?

p+n+d=120

n=2p-14

d=3p-22

p+(2p-14)+(3p-22)=120

6p-36=120
6p=156
p=26

n=2(26)-14
n=52-14
n=38

d=3(26)-22
d=78-22
d=56
